3.5.6.4 Tilt and Z Axis Limitations
The allowable tilting angle depends on both Z-axis position and specimen size. A diagram of
the relationship between allowable tilt angles for various Z positions is shown below.
The values shown here represent the case where the specimen height is set in the Standard
position by uising a level gauge. The allowable tilting angles for ∅200 mm specimens
represent the case where the range over which the specimen can be moved in an X direction is
restricted to 30 mm – 45 mm. The use of an optional signal detector (inserted into the
specimen chamber) is subject to further restrictions. For further details on this topic, the
operating instructions on the optional detector should be consulted.
